LUMBER-BOOM.

SPECIFICATION forming part of Letters Patent No. 445,107, dated January20, 1891.

Application filed August 28, 1890 Serial No. 363,272. (No model.)

To LLZZ whom it may concern:

Be it known that I, ALSON l1. \VILLEY, a citizen of the United States ofAmerica, residing at Bluff City, in the county of Sullivan and State ofTennessee, have invented certain new and useful Improvements inLumberl3ooms; and I do hereby declare the following to bcafulhelear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

This invention relates to improvements in logbooms.

The object of the invention is to provide a log-boom for catching andretaining the floating logs, the main portion of the boom being made upof fixed pens, between which are rigidly secured upon cables andretained in place a series of vertical posts which extend below thewater to the bottom, and with the pens make up a pocket, within whichthe logs are confined, said device being adapted to be used with a sheerloosely connected to the upper pen at upper end of pocket and adapted tobe stretched diagonally across the stream, for running the logs into thepocket.

In the accompanying drawings, forming part of this specification, Figure1 is a side View of a portion of a log-boom constructed in accordancewith my invention. Fig. 2 is a plan view. Fig. 3 is a sectional viewthrough one of the vertical posts.

A refers to a stream of water, the current of which flows in thedirection shown by the arrow, and l3 l3 refers to the shore on each sideof the stream. Adjacent .to one of the shores is built a series of fixedpens C C, which are made up of logs or timber and filled with stone.Into or through these pens pass a series of cables a. \Vhen said cablesterminate in the pen, theyare made fast toacross-piece, and under allcircumstances these cables are confined therein. The cables arestretched as tight as practicable, and by means of bent bolts the postsD D are securely attached thereto. To the upper pen D is secured a sheerE, of ordinary construction, which is adapted to be swung diagonallyacross the stream and is made fast to a suitable fixture or windlass. Acable e may also be attached to the upper end of the sheer E for drawingthe same to the opposite bank when not em ployed for guiding the logsbetween the sheer and pens into the pocket. By providing the posts withperforations, through which pass the bolts, having bent ends I),attached to said posts by nuts, these bolts may be loosened to permitthe posts to be adjusted upon the cables, as when the bolts are loosenedthe posts can be slid upon the cables to leave a space to pass thecollected logs out into the stream.

This boom is designed more especially for swift-running streams withrocky bottoms, and can be made the proper height to accommodate the riseof water. The cables being stretched through the pens the whole lengthof the system and the uprights going to the bottom of the stream, makesthe system very strong, and entirely stops logs from working through andunder the booms, as is always the case with the old-fashioned floatingboom. Logs can be jammed into a pocket of this kind with the swiftest ofwater without any danger of any loss whatever, as the logs can pile insolidly from the bottom of the river to the tops of the pens and by thissystem be securely fenced in and safe, where with a floating boom thelogs would sometimes nearly all of them be driven through inunderfloating booms and lost.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a lumber-boom, a series of rigid structures or pens permanentlylocated in the bed of a stream and extending from said bed above thewater-level, cables rigidly secured to said pens, a fence made up ofvertical posts, which are secured to the cables between the pens, saidposts extending from the bed of the stream above the water-level, and afloating sheer secured at one end to the fixed pen, substantially asshown, and for the purpose set forth.

2. In a lumbenboom, a series of pens or permanent and rigid structuresbuilt in the bed of the stream so as to extend above the water-level,cables rigidly secured to the pens and stretched between them, a seriesof vercured. t0 the posts so as to grasp the cables tical posts securedto said cables, so as to be the stream, the parts being organized sub-10 maintained in a; vef'tieztl position, said posts stgntially as setferth;
